Hi, I came across with the same issue with mobo genie last month. The trick they used was to use the same icon for downloads as their downloader. To remove this:

1. Make sure you have uninstalled mobo genie market.
2. Go to App, and swipe until you see "All" you will see 2 Downloads icon there.
3. The Downloads with no size is the legit one. Keep it, if you long press and select App info you will see that it's something related to your firmware.
4. The 2nd Downloads icon is the culprit, with a version of 2.02xx. Long press it, select App info then uninstall.

Hope this helps.
